Osg 300-1575 Chucking Reamer 4mm Solid Carbide

Product Description

The OSG 300-1575 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. With a 4.00 mm (0.1575 inch) reamer diameter and a tight tolerance of +0.0001 to +0.0004 inches, this tool delivers consistent, accurate bore sizing across a range of workpiece materials. The 64 mm overall length accommodates standard chuck setups, while the 19 mm flute length provides adequate chip clearance for typical through-hole and blind-hole reaming operations. Machinists and tool-and-die professionals use this reamer as a finishing step after drilling or boring to achieve the precise fit required for dowel pins, bearings, and precision assemblies.

The 300-1575 is suited for general machining applications in both job shop and production settings. Its bright, uncoated finish makes it appropriate for use on ferrous and non-ferrous metals where coating interaction is a concern. The straight shank is compatible with standard drill chucks and collet holders. This reamer is part of OSG Series 300D and is positioned as a standard carbide reamer for general machining applications where dimensional accuracy and surface finish are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in production reaming
• Straight flute geometry with right-hand cutting direction
• 4-flute design balances chip evacuation and surface finish quality
• Bright, uncoated finish suitable for a broad range of workpiece materials
• Straight-cylindrical shank fits standard drill chucks and collet holders

Compatibility

Designed as an OEM-style replacement and standard-use chucking reamer for general machining applications in the OSG Series 300D lineup, compatible with machine setups accepting a straight-cylindrical shank.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist familiar with cutting tool setup and machine tool operation. Secure the straight shank firmly in a drill chuck or collet holder and verify runout before use, as excessive runout will negatively affect hole tolerance and tool life. Always power down and lock out the machine before changing tooling. Follow applicable shop safety standards and the machine manufacturer's guidelines for spindle speed and feed rate selection.
